WebDec 30, 2024 · A titration curve is a plot of the concentration of the analyte at a given point in the experiment (usually pH in an acid-base titration) vs. the volume of the titrant added.This curve tells us whether we are dealing with a weak or strong acid/base for an acid-base titration. The curve around the equivalence point will be relatively steep and smooth when … WebFeb 26, 2024 · As RbOH dissociates into Rb 1+ and OH 1-, the OH 1- concentration is also 1.9 x 10 -3. [H 1+] [OH 1-] = 10 -14, so the [H 1+] = 10 -14 / 1.9 x 10 -3 = 5.3 x 10 -12 . Take the negative log of this to get pH = 11.3. The log of 1.9 x 10 -3 is -2.72, but pOH is the negative of this which is 2.72. pH + pOH = 14, so you can calculate pH from this also.
